UNITED STATES ALFRED W. E. HELLYER, OF OTTAWA, ONTARIO, CANADA.

MOLD.

Application filed October 18, 1922.

To all whom it may concern:

Be it known that I, ALFRED 1V. E. HELLYER, a citizen of the Dominion ofCanada, and resident of Ottawa, in the county of Carleton and Provinceof Ontario, Dominion of Canada, have invented certain new andusefulImprovements in Molds, of which the following is a specification.

This invention has relation to certain new and useful improvements inmolds.

An object of the invention resides in the provision of a brick moldwhich will be constructed in such a manner as to form channels orgrooves in one or more places as the bricks are molded so as to presentornamental faces or surfaces which may be turned out to form one side ofthe wall constructed from the bricks.

Another object of the invention resides in the provision of a brick moldof the character stated which will include channel or groove formingwires carried on certain walls of the mold compartments and securelyheld in position during use of the mold.

A further object of the invention resides in the provision of a mold ofthe character stated which will be of simple and inexpensiveconstruction as well as highly eflicient in use, strong and durable.

The invention has for a still further object the provision of a mold oithe character stated in which the channel or groove forming members willhave their ends fastened in such a manner to the walls of the moldcompartment as to securely retain the channel or groove forming membersin proper position.

With the foregoing and other ob iects in view as will appear as thedescription proceeds the invention consists in the novel construction.combination and arrangement of cooperating elements as hereinafter morespecifically set forth. claimed and shown in the accompanying drawingsforming a part of the present application and in which:

Fig. 1 is a perspective view of the brick forming mold.

Fig. 2 is an enlarged transverse vertical section. substantially on theplane of line 2-2 of Fig. 1, looking in the direction indicated by thearrows.

Fig. 3 is an enlarged detail longitudinal vertical section substantiallyon the plane of line 3-3 of Fig. 1, looking in the direction indicatedby the arrows.

Serial No. 595,371.

Fig. l is an enlarged fragmentary detail vertical section showing aslightly modified form of the invention.

Referring more in detail to the drawings in which similar referencecharacters desiguate corresponding parts throughout the several views,designates in general the mold which includes longitudinal side members6 and transverse end handles 7 secured between the opposite ends of thelongitudinal side members 6, as shown clearly in Fig. 1. The mold 5 isdivided into several compartments or sections, by the transversepartition members 8 and separate bottom members 9 are provided for thevarious compartments or sections. The longitudinal edges of the moldstructure are braced and strengthened by the re-inforcing andstrengthening strips 10 secured over the frame and extending around theends of said longitudinal members while similar members 10 extend acrossthe ends of the bottom members 9. The transverse partitions 8 are alsore-intorced by the re-inforcing and strengthening strips 11 secured onthe upper edges thereof and interlocking at their ends with thelongitudinal re-intorcing and strengthening strips 10. This is the usualconstruction of this form of mold. and the connection of the variousparts will need no further detailed description.

In order to adapt this type of H'lOlCl to the formation of ornamental orgrooved bricks. the groove or channel forming wires 12, 13 and 19 areemployed. The wires 12 are extended in spaced relation transversely orvertically of the inner face of one longitudinal side member 6 of thestructure. with the upper and lower ends 15 ot the wires 12 bent overand secured in the upper and lower edges of the side frame member 6. Anappropriate number of wires 12 are employed at one end of eachcompartment or section of the mold. The wires 13 are provided on everysecond transverse partition member 8 and are composed. of substantiallyU-shaped wire members 16 having their central or bight portions extendedtransversely beneath the transverse partition 8 with the main portionsof the wires brought upwardly in spaced relation along the oppositefaces of the transverse partition 8 and the ends 17 bent downwardlytoward one another over the upper edge of the transverse partition 8 andextended into the same, as

shown clearly in Fig. 33. It is evident from Figs. 2 and 3 that theupper ends 15 of the wires 12 are held in proper position by thelongitudinal reinforcing and strengthening strips 10, while thereinforcing and strengthening strips 11 retain the upper ends 17 of thesubstantially U-shaped wires 16 in proper position in the upper edges ofthe transverse partition 8. It is also evident that the reinforcing andstrengthening strips 10 and 11 may be secured in place by screws 18other suitable securing members.

In Figs. 1 to 3 l have shown the trans verse groove or channel formingwires 19 which extend in spaced relation across the bottom members 9 ofthe various sections. The ends 20 of the wires 19 are bent downwardlyaround the longitudinal edges of the bottom members 19 and then driveninto the downwardly and inwardly bevelled portions 21 of thelongitudinal edges, as shown clearly in Fig. 3.

In Fig. 4, the modified form is disclosed which comprises upstandingchannel or groove forming wires 22 having angular faces 23 instead ofrounded faces, as shown in the preferred form. The ends 2a of thechannel or groove formingwires 22 are bent around and driven into thelower edges of the upstanding frame members 25, on the inner face ofwhich the wires 22 are positioned, thereby securely anchoring the lowerends 24 of the wires 22. It is to be understood that the upper ends ofthe wires 22 may be similarly anchored so as to securely hold the wires22 in proper position.

Corresponding bottom wires 26, having angular upper faces 27 are mountedtransversely of the bottom frame member 28 of each section of the mold,as shown in Fig. 4. It will be apparent that when employing the wires ofthe character shown in Fig. 4-, a different shaped channel or groovewill be formed in the faces of the bricks molded in the compartment orsections of the mold and it is apparent that the form of wires may bevaried as desired, according to the result desired to be obtained.

lVhile the mold has been disclosed as hav ing vertical wires on side andend members of the sections and transverse wires on the bottom membersof the sections, longitudinally or angularly positioned wires may beemployed to produce grooves or channels extending longitudinally orangularly of the faces of the bricks, if preferred. It is also to beunderstood that the wires may be employed for only one face or for anumber of faces of the brick, as desired. Furthermore, other means maybe employed for ornamenting or finishing one or more faces of the brickwhile molding the same.

Therefore, I do not wish to limit myself to the structure disclosed.

This principle may be applied to various forms of molds for theproduction of brick.

building blocks, cement forms and the like.

While the preferred embodiment of the invention has been described it isto be understood that minor changes in the details of construction,combination and arrangement of co-operating elements may be resorted towithin the scope of what is claimed without departing from the spirit ofthe invention.
